Shell Helix Ultra Professional AP-L 0W-20
Shell Helix Ultra Professional AP-L 0W-20 is a premium fully synthetic motor oil developed to meet the demanding lubrication requirements of modern high-efficiency gasoline and diesel engines. The oil is formulated using advanced synthetic base oils combined with carefully balanced additive technology to provide reliable engine protection, improved fuel efficiency and consistent performance across a wide range of operating conditions. It has been specifically designed to meet the requirements of modern Peugeot and Citroën engines that require advanced low-viscosity lubricants.
One of the key advantages of Shell Helix Ultra Professional AP-L 0W-20 is its ability to deliver excellent fuel efficiency. The oil has been tested using the ACEA M111FE fuel economy procedure and demonstrates a minimum fuel efficiency improvement of approximately 3.5 percent compared with industry reference oils. Reduced internal engine friction allows moving components to operate more efficiently, helping engines achieve improved fuel economy while maintaining strong lubrication protection. These benefits are particularly important for modern vehicles designed to meet increasingly strict fuel economy and emissions regulations.
The oil also provides strong protection against engine wear. Engine components such as pistons, camshafts and bearings operate under high loads and temperatures during normal engine operation. Shell Helix Ultra Professional AP-L 0W-20 forms a durable lubricating film that reduces metal-to-metal contact between moving parts. This protective film helps minimise wear and supports long-term engine durability while ensuring reliable lubrication performance throughout the oil drain interval.
Another important benefit of the oil is its ability to maintain engine cleanliness. Combustion by-products and degraded oil can accumulate inside the engine over time, leading to sludge and deposit formation. Shell Helix Ultra Professional AP-L 0W-20 is formulated to resist deposit formation and keep internal engine components clean. The oil successfully passes several engine cleanliness tests including the Sequence VH sludge test and the DV6C oil dispersion test, demonstrating its ability to maintain clean engine internals and support efficient engine operation.
Shell Helix Ultra Professional AP-L 0W-20 is also designed to support modern emission control systems. The oil is formulated for use in engines equipped with diesel particulate filters and gasoline engines using three-way catalytic converters. Its formulation helps protect these emission systems by reducing deposit formation and maintaining efficient exhaust gas flow, supporting compliance with Euro 6 emission regulations.
The oil meets the technically demanding Peugeot PSA B71 2010 engine oil specification, which requires lubricants to pass manufacturer-specific durability and wear tests including the DW10B wear test and EP6CDT endurance testing for gasoline direct injection engines. It also meets the API SP industry specification, confirming its ability to deliver reliable lubrication performance in modern engine designs.
Physical characteristics include a kinematic viscosity of approximately 44 mm²/s at 40°C and 8.1 mm²/s at 100°C with a density of approximately 838 kg/m³ at 15°C. The oil has a flash point of approximately 234°C and a pour point of approximately –48°C, supporting reliable lubrication performance across a wide range of operating temperatures and driving conditions.
